Solved Problem with WiFi Router

Need your help/advice here regarding a WiFi Router. Friend of mine told me that before he goes to sleep he turn off all his network devices (Modem and WiFi Router) but when he turn them ON again in the morning he has to wait to long to get WiFi signal? Devices turned on and he has signal on his mobiles but after 4-5 minutes he can browse on internet? Any advice/help will be great.

As I red to many articles regarding to some Computer experts WiFi signal is dangerous to leave it ON till we are sleeping? For that reason many people here are turning them OFF before go to bed (me also) but I'm not facing this king of problem?

Often all the devices can be powered on at the same time with no evident issues. But when there are any problems one should follow recommended practices to try to avoid the problems or to trouble shoot them.

Power on the modem and wait for it to "settle." Then power on the router and wait for it to indicate that it is synced with the modem and ready to perform. Obviously this means you have to watch the LEDs and understand what they are telling you. Then power on devices one at a time. By doing this the network should be operating in the minimum time or you should have an idea what device is struggling.

If your friend does not want to trouble shoot then assume it is what Andrew just posted. With that assumption the fix is to keep the modem and router on and connected or to power them up with the proper procedure.
